Your requirements could not be resolved to an installable set of packages. Problem 1 - spatie/laravel-backup[8.1.0, ..., 8.1.11] require ext-zip ^1.14.0 -> it is missing from your system. Install or enable PHP's zip extension. - Root composer.json requires spatie/laravel-backup ^8.1 -> satisfiable by spatie/laravel-backup[8.1.0, ..., 8.1.11]. To enable extensions, verify that they are enabled in your .ini files: - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode. Alternatively, you can run Composer with `--ignore-platform-req=ext-zip` to temporarily ignore these required extensions.
